Abstract
A roll is described, particularly a roll for crushing or de-agglomerating different materials. It can be used in all situations where deformations of the roll ends, in association with a constant roll gap, constitute a problem, particularly at high roll loadings. The object of the invention is to further develop a roll of this type so that variable adjustments or a constant roll gap are possible at different operating stages. This object is achieved in that the roll consists of a core and a roll shell, wherein elastic elements are disposed between the core and the roll shell.
